What is EWS and what is it for?
EWS stands for Early Warning System from the USPS. EWS addresses are flagged by Address Check when they are scheduled for inclusion in the USPS database but are not added yet. The addresses are typically new high rises, or new housing subdivisions that are being assigned deliverable mail addresses. The EWS file when present in the Address Object directory ensures that addresses not present in the USPS master file will not be eliminated or coded inaccurately. The EWS file is updated weekly and can be downloaded via the Melissa Data FTP site to give customers the freshest new address information.
